Kvass (or Kvas) is a “beer-like” fermented beverage that is made primarily from rye. It is low in alcohol and is often flavoured with local ingredients such as herbs or fruit.

Kvass is essentially the national drink of Russia (where is dominates cola) and is also popular in other Eastern European nations.
